The University of Cincinnati (UC) Cosmetic Science program recently announced the launch of the new Hygienic Manufacturing of Cosmetic Products Graduate Certificate, which comes as the cosmetic industry attempts to transition using more natural ingredients in its products. The Personal Care Products Council (PCPC), which is made up of top figures in the cosmetics sector, helped develop this new certificate.This new direction came about after experts in the industry discovered that natural preservatives within these natural ingredients lack the strength to undergo the rigorous manufacturing processes that chemical ingredients traditionally undergo themselves.
